Natural selection acts upon the individual organism, whilst evolution occurs at the population level. The environment selects for organisms best adapted for highest survival and reproductive success. Natural selection requires three key things - variation, inheritable traits, and differential survival/reproduction.
Species will produce more offspring than the environment can support(carrying capacity), and the population tends to be fairly stable until resources are limited. A struggle for existence is created, and natural selection ensures that weaker traits die out while stronger traits live on. Organisms show variation in characteristics, and that variation is heritable. Survival depends on inherited traits, and unequal survival/reproduction leads to adaptation and evolution.
Therefore, while the individual organism can adapt, the population is what actually evolves.

Does evolution occur at the level of the organisms?
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
What is the smallest group of organisms in which evolution can take place?
The smallest group of organisms wherein evolution can take place is a population. This is because all methods of evolution require chromosomes from more than one organism.
What level of evolution of magikarp?
Magikarp evolve at level 20.
Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
What would happen if there was zero variation between all of the organisms on earth?
Evolution cannot occur.
The smallest unit in which evolution occurs is?
The smallest unit in which evolution occurs is a population.
Does evolution occur at the level of the organisms?
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
What is evolution on the smallest scale?
A POPULATION
What is divergence in evolution?
Divergence is the growing apart of two lineages - lines of descent. Divergence may occur at the morphological, behavioural and developmental level, and will always occur at the genetic level, at least when two lineages are reproductively isolated from one another.
What is the smallest group of organisms in which evolution can take place?
The smallest group of organisms wherein evolution can take place is a population. This is because all methods of evolution require chromosomes from more than one organism.
Does Evolution occur slowly?
yes.
Why are adaptations evidence of evolution?
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
What level does Venipede evolve in pokemon white 2?
my venipede evolved at level 32 BUT, definitely it evolves at a lower level(oh i forget to mention that how do i know it evolve at a lower level? well that's because my venipede got like 20 levels in 1 battle)(don't ask me how but i didn't do it with hacks) good day people.
How are organisms related to evolution?
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
What is Jedstar's evolution level?
Jedstar's outstands and his terrible scream gives him and evolution level of 9!
What group is the smallest level of classification in biology?
Species is the smallest level of classification in biology.
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
